[gmx-users] How can i install DSSP for gromacs on centos6?

[Homa rooz]

Hi there

I tried to execute dssp for gromacs 4.5.7 by following this instruction:

#sudo wget ftp://ftp.cmbi.ru.nl/pub/software/dssp/dssp-2.0.4-linux-amd64
<https://www.researchgate.net/go.Deref.html?url=ftp%3A%2F%2Fftp.cmbi.ru.nl%2Fpub%2Fsoftware%2Fdssp%2Fdssp-2.0.4-linux-amd64>
-O /usr/local/bin/dssp

#sudo chmod a+x /usr/local/bin/dssp

#export DSSP=/usr/local/bin/dssp

then I run g_do_dssp and I got this error:

-----------------------------------------------------------------

Program g_do_dssp, VERSION 4.5.7
Source code file: /builddir/build/BUILD/gromacs-4.5.7/src/tools/do_dssp.c,
line: 572

Fatal error:
Failed to execute command: /usr/local/bin/dssp -na ddKnNFex ddYd8PhB >
/dev/null 2> /dev/null

-------------------------------------------------------

It also makes some files like "ddYd8PhB"!

I have tried two different binary file but it didn't work. In addition
there is a binary "g_do_dssp" from gromacs package . How can I point it to
export dssp?

plz help me to fix that problem
